6 Claims. (Cl. -13) This invention relates to a bed construction of the type which includes a foldable sectional frame adapted for use in one position as a bed and in another position as a seat.

In bed constructions of this character, the foldable frame supports a mattress which is disposed in extended condition when the bed frame is in bed forming relation and which is foldable with the foldable frame into folded relation when providing a seat. When the foldable frame is in collapsed folded condition the outersection is inverted and is adapted to receive one or more seat cushions to provide a seat. This type of bed construction necessitates the use of a mattress which is foldable into doubled over relation with the folding of the frame.

In order to avoid the use of a mattress of said character, anobject of the invention is to provide a mattress section which is swingable with the foldable frame to dispose the same face of the mattress section uppermost when in both bed forming and seat forming positions.

Still another object of the invention is to swing the mattress section with the movement of the outer section of the foldable frame from the aligned bed forming relation to an inverted overlying spaced relation with an intermediate section of the frame and with the same face of the mattress section disposed uppermost in both of said relations of the foldable frame.

Still another object of the invention is to provide a bed construction in which the mattress section constitutes a support for one or more seat cushions when the foldable frame is in seat forming relation.

With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.

. In the embodiment of the invention illustrated in the drawings, the article of furniture constitutes a love seat, chair, couch and the like in one position and a full size bed in another position. The article of furniture includes a suitable furniture frame 10 composed of opposite side panels 11 and 12, a back 13, a forward panel 14 rigidly connected between the side panels 11 and 12, and a movable panel 15. Swingably connected with the furniture frame 10 is a foldable metal frame 17 composed of a plurality of foldable sections. As illustrated, the foldable frame 17 includes an inner section 18, a long intermediate section 19, a short intermediate section 20 and an outer end section 21. Each of said sections is of iron construction and the sections are adapted to be disposed in aligned bed forming relation, the sections 18 and 19 having a wire mesh spring 22 for supporting a loose mattress 23, while a mattress section 24 is affixed to brackets 25 carried by the outer section for movement therewith.

Theinner section 18 consists of spaced parallel side rails 26 which are connected together at their inner ends by a cross bar 27 and are pivotally connected on pivot pins 28 to opposite side rails 29 of the long intermediate section 19. The side rails 29 are connected together at their outer ends by a cross bar 30 and are pivotally connected on pivot pins 31 to opposite side rails 32 of the short intermediate section 20. The side rails 32 of the short intermediate section 20 are pivotally connected to the side rails 33 of the outer end section 20 on pivot pins 34, the side rails 33 being connected together at their outer ends by a cross bar 35. The wire mesh spring is secured to and stretched between the inwardly directed flanges of the side rails 26 and 29 and between the cross bars 27 and 30. The inner section 18 is swingably connected with the furniture frame by bent links 37 which are pivotally connected thereto at their lower ends on pivot pins 38 and at their upper ends said bent links are pivotally connected on pivot pins 39 to downturned ends of flat bars 40 riveted or otherwise secured to the side panels 11 and 12 of the furniture frame 10.

When in bed forming relation the foldable frame projects from the furniture frame 10 and is supported by pairs of legs 42 and 43. The legs 42 are arranged one on each side of the foldable frame and are pivoted on the pivot pins 31 to the intermediate sections 19 and 20, while the legs 43 are pivoted at their upper ends to the side rails 33 of the outer end section 21 on pivot pins 44. The legs 43 are swingable into substantially parallel relation with the outer end section 21 by means of links 45 which are downturned at their inner ends and are pivoted to the vertical flanges of the side rails 32 respectively of the short intermediate section 20 on pivot pins 46. At their outer ends the said links are pivotally connected on pivot pins 47 to latch plates 48 which are riveted or otherwise affixed to the upper ends of the legs 43 respectively.

The legs 42 are swingable into substantially parallel relation with the long intermediate section 19 with the collapsing of the foldable frame into folded relation within the furniture frame as shown in Fig. 7 of the drawings by means of a link structure arranged one on each side'of the furniture frame. Each of said link structures includes a link 50 pivotally connected at its outer end to one of the legs 42 on a pivot pin 51 and at its inner end the said link is pivotally connected to a bent link 52 on a pivot pin 53. The bent link 52 is pivotally connected to a side rail 29 of the intermediate section 19 on a pivot pin 54 and at its forward end the said link is pivotallyconnected to the end of a straight link 55 on a pivot pin 56. The straight link 55 is pivotally connected to the side rail 26 of the inner section 18 on a pivot pin 58 with the extreme inner end of said link being pivotally connected on pivot pin 59 to a link 60 pivotally connected on a pivot pin 61 to the bent link 37. Pivotally connected to the straight links 55 adjacent the outer ends thereof are links 63 which are aflixed at their inner ends to short rigid bars 64. The bars 64 are pivoted on pivot pins 65 to the outer offset ends of straps 66 which are bolted or otherwise affixed to the inside faces of the side panels respectively of the furniture frame 10. Each of the links 63 is tensioned by springs 68 aflixed at their ends to brackets 69 and 70 pivotally connected respectively to the inner end of the strap 66 and the free end of the bar 64.

The outer end section 21 is swingable into overlying spaced relation with the long intermediate section 19 as shown in Fig. of the drawings to dispose the short intermediate section substantially vertical and in order to limit the movement of the outer end section 21, links 72 are provided whichare pivoted to the vertical flanges of the side rails 32 of the short intermediate section 31 on the pivot pins 46 and at their inner ends the said links have pin and slot connections 74 with the vertical flanges of the side rails 29 of the long intermediate section 19. Constructed in this manner the outer end section is swingable into overlying relation with the long intermediate section 19 and the outer end of the foldable frame may then be elevated to the inclined position shown in Fig. 6 of the drawings and then swung downwardly to turn the links 63 rearwardly on the pivot pin 65 to thereby lower the long intermediate section 19 into substantially horizontal relation within the furniture frame 10 and to dispose the inner section 18 in vertical or upright relation as shown in Fig. 7 of the drawings.

With the collapsing of the foldable frame into folded relation within the furniture frame 10, the mattress section 23 is folded therewith to dispose the portion thereof carried by the inner section in upright relation and the portion carried by the long intermediate section in substantially horizontal relation. The mattress section 24 is moved from the position shown in Fig. 2 of the drawings to the position shown in Fig. 7 with the same face uppermost for supporting one or more seat cushions when in the position shown in Fig. 7 of the drawings. The said section is supported by the brackets which are pivoted to the side rails 33 of the outer end section 21 on the pivot pins 76. The brackets 25 are also pivoted to the outer ends of links 77 on the pivot pins 78 with the lower ends of the links being downturned and pivoted on the pivot pins 79 to the vertical flanges of the side rails 32 of the short intermediate section 20. The pivot pins 76 and 78 are oppositely disposed whereby the mattress section 24 is elevated with the upward movement of the outer end section 21 to dispose the mattress section in forwardly inclined relation as shown in Figs. 3 and 4 of the drawings. The mattress section is thus moved into overlying relation with the mattress section 23 and with the downward movement of the outer end section into parallel relation with the long intermediate section 19, the mattress section 24 is disposed in substantially horizontal relation as shown in Fig. 5 of the drawings.

The movable panel member 15 consists of spaced transversely extending parts 81 and 82 which are respectively afhxed to bracket members 83 and 84. The bracket members 83 are riveted or otherwise atfixed to the vertical flanges of the side rails 32 of the short intermediate section 20, while the bracket members 84 are pivoted to the bracket members 83 on pivot pins 85, and the bracket members 84 are tensioned by coil springs 86 and 87 affixed to the outer ends thereof and to the bases of the bracket members 83 and to lugs 88 affixed to the side rails 33 of the outer end section 21. The springs 86 and 87 tension the part 82 of the panel 15 to retain the same in normally spaced relation from the part 81 and to provide a resiliency to the upper portion of the said panel when the same is in vertical position closing the forward portion of the furniture frame 10 above the fixed panel 14 as shown in Fig. 7 of the drawings. The panel member 15 is provided with upholstery covering 89 which permits of the free movement of the parts 82 thereof.

While the preferred form of the invention has been shown and described herein, it is to be understood that the same is not so limited but shall cover and include any and all modifications thereof which fall within the purview of the claims.
